YC150U Interferometer - Workstation
The YC150U laser interferometer workstation is an upright optical measurement system with a clear aperture of φ152.4 mm, high-precision imaging, and good vibration isolation. It measures surface form and radius of curvature of medium-to-large optical lenses. An enclosed test chamber reduces airflow effects from external factors. A multidimensional motorized sample platform allows optics to lie flat during testing, reducing mounting stress. If the full aperture cannot be tested in one measurement, multiple regions can be measured by adjusting lens pitch according to the actual conditions, as shown below.
